Answer: 5. Tundra

Explanation:

Tundra is a biome that is located in the coldest regions of the world. This is characterized by short growing seasons and low temperatures. The plants growing in these regions are short perennials. The soil in these regions is frozen and nutrition poor. Therefore, plants growing here are simple like lichens, mosses, sedges, grasses and dwarf woody plants as the soil and weather conditions cannot support the growth of deep rooted plants and trees.

Answer:

The chemical formula for the molecule is $C_4H_9O_2$

Explanation :

Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.

In the structural formula, the lines are used between the atoms.

As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.

Thus, the chemical formula for the given molecule will be, $C_4H_9O_2$

A shopper pushes a 5.32 kg grocery cart

Juli2301 [7.4K]

Answer:

$\text { acceleration of the cart is } 10.94 \mathrm{m} / \mathrm{s}^{2}$

Explanation:

According to “Newton's second law”

“Force” is “mass” times “acceleration”, or F = m× a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass

Force = mass × acceleration

$\text { Acceleration }=\frac{\text { force }}{\text { mass }}$

Given that,

Mass = 5.32 kg

$\text { Force }=12.7 \mathrm{N} \text { forces at }-28.7^{\circ}$

$x=-28.7^{\circ}$

F = 12.7N

Normal force = mg + F sinx,

“m” being the object's "mass",

“g” being the "acceleration of gravity",

“x” being the "angle of the cart"

$\mathrm{g}=9.8 \mathrm{m} / \mathrm{s}^{2}\text { (g is referred to as the acceleration of gravity. Its value is } 9.8 \mathrm{m} / \mathrm{s}^ 2 \text { on Earth })$

To find normal force substitute the values in the formula,

Normal force = 5.32 × 9.8 + 12.7 × sin(-28.7)

Normal force = 52.136 + 12.7 × 0.480

Normal force = 52.136 + 6.096

Normal force = 58.232 N

<u>Acceleration of the cart</u>:

$\text { Acceleration }=\frac{\text {Normal force}}{\text { mass }}$

$\text { Acceleration }=\frac{58.232}{5.32}$

$\text { Acceleration }=10.94 \mathrm{m} / \mathrm{s}^{2}$

$\text { Therefore, "acceleration of the cart" is } 10.94 \mathrm{m} / \mathrm{s}^{2}$

valkas [14]

Answer:

In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.

Explanation:

There are two ways to connect electrical circuits, in series and in parallel.

Series circuits have the problem that when one element is damaged, the entire circuit is interrupted and runs out of power.

In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.

In Breaker it is connected in series so that when some maintenance is needed, all the energy can be interrupted simultaneously and if some equipment tries to consume a lot of energy, the circuit prevents this action by interrupting the energy of the entire circuit
